Main features
Advanced technical principles
* Humidity control adopts the principle of moisture occurrence by shunt method, which greatly shortens the time required for stability and improves the verification efficiency compared with the principle of humidity occurrence by double temperature method.
* Temperature control using liquid bath constant temperature plate heating technology, liquid medium heat radiation, temperature more constant, temperature field more uniform
 * The unique air circulation design in the measuring chamber ensures no dead angle air flow, and adopts frequency conversion technology to speed the fan to ensure that the internal temperature field is uniform at low speed;

Whether your testing is for R&D, clinical trials or ongoing stability, the TEMPO stability chamber provide a stable temperature & humidity condition environment for worry-free operations with a control system that is easy to operate. TEMPO make stability chamber is designed as per ICH guidelines and are manufactured to comply with requirements in the industries. Stability testing is an integral part of formulation development. It helps to generate information, which permits well-considered proposals to be made for the shelf life of drug substances and products and recommended storage conditions.

The purpose of stability testing is to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, and to establish a re-test period for the drug substance or product under recommended storage conditions. Hence, the pharmaceutical stability chamber serves as an important quality attribute for the product.

Grande Expertise in Humidity Control
Controlling humidity in a small environmental chamber can be especially challenging. Grande expertise in humidity control brings intelligent design that is carefully integrated into the Criterion chambers. The humidity subsystems are designed for reliability, convenience, and performance:
An external steam generator allows expanded range and is easy to maintain.
A separate de-humidification coil improves low humidity control and range.
Wet-bulb humidity sensor is a �??primary measurement method�?? for accuracy. It is also economical, easy to maintain, and reliable because it has no risk of failure due to over-saturation. (Read why analog is preferred over digital.)
Direct water supply connection is standard, with options for water filtering and recirculating water tank.
